FAQ

I've bought a door handle set that looks great online, but it’s too small for my doors. What should I do?

Measure the backset of your existing doors – this is the measurement from the edge of the door to the center of the hole where the spindle sits. Ensure any new handles you purchase match this backset size before ordering to avoid having to re-mortgage the house!

Some sets have lots of extra features I don't need, like keyhole locks and multiple turn options. Is it worth paying extra for these?

Carefully consider your security needs – a simple lever handle will often suffice and save you money. Only opt for additional features if you genuinely require them, rather than being swayed by marketing hype.

I've purchased a door handle set, but I’m struggling to fit it myself. Are there any readily available tools or instructions?

You'll typically need a screwdriver and possibly a small Allen key, depending on the specific design. Most manufacturers provide basic fitting instructions, which you can usually find online alongside the product details.

I’ve noticed some sets don't include any screws or fixings. What am I missing?

Always check the product listing carefully to confirm it includes all necessary hardware – this often involves fixing plates, screws, and potentially wall anchors. If not, factor in the cost of these extras.

I’m replacing a traditional mortise handle with a lever handle. Does this require any special skills?

While relatively straightforward, ensure you understand how to properly align the lever spindle within the door rose plate for smooth operation and minimal adjustment after installation.

My doors are quite old and have unusual hole sizes. Will I be able to find a suitable replacement?

Measure the diameter of the existing holes accurately, paying attention to any irregularities. Specialist suppliers may offer bespoke handles or adapters if standard sizes don’t work.

I’ve bought a handle set that looks stylish but feels flimsy. What could be going wrong?

Check the material – brass and stainless steel are generally more durable than cheaper zinc alloys. Consider the weight and construction of the handle itself when assessing quality.

What about hidden fixings? Are they always a good idea for security?

Hidden fixings can offer enhanced security, but ensure you use appropriate screws and wall anchors suitable for your wall type – incorrect installation weakens their effectiveness.

I’m concerned about the finish of the handle tarnishing. What can I do to protect it?

Regularly wipe down brass or polished metal handles with a soft cloth and a specialist metal polish designed for that material to maintain their shine.

If something goes wrong with the handle after installation, who do I contact for support?

Refer to the manufacturer’s warranty information for details on repairs or replacements, which will be outlined in the product listing or documentation. Amazon's standard returns policy also applies if you are dissatisfied.

In depth

It’s easy to get swept up in the visual appeal of door handles and knobs – they're a small detail that can significantly impact a room’s overall aesthetic. However, overlooking crucial considerations beyond just style can lead to frustrating problems down the line. Many UK homeowners make mistakes when selecting this seemingly simple hardware, often resulting in an expensive fix or an ultimately unhappy installation. Let’s delve into some of these common pitfalls and explore how to approach your purchase with a more considered eye.

One of the most frequent errors is failing to accurately measure the existing door mortice hole – the space where the handle sits. This seems obvious, but it's astonishingly common for buyers to assume all handles are standard size. Mortice plates come in various widths and depths, dictated by the manufacturer’s design and the specific door they’re intended for. Ordering a handle that’s too small won’t simply look awkward; it will be impossible to install correctly, likely requiring an entirely new mortice plate cut into the door – a significantly more involved and costly undertaking than simply selecting the right size from the outset. Before ordering anything, meticulously measure the existing hole with a fine-gauge ruler or tape measure. If you’re unsure about the dimensions or are replacing an old handle, consider taking a sample of the existing mortice plate to a specialist ironmongery supplier for accurate measurement and advice – many offer this service free of charge.

Beyond the physical size of the handle itself, buyers frequently overlook the importance of choosing the correct type of mechanism. There’s a bewildering array of locking mechanisms available: lever handles (the most common), knob-operated, push-to-open, even concealed options with integrated smart home technology. Often, homeowners will purchase a handle with an elaborate, high-security locking system that they then rarely use. This means paying a premium for features that sit idle. Before committing to a particular design, honestly assess your needs. Do you require robust security? Is a complex locking mechanism essential, or would a simple lever handle suffice? Consider the age and type of your door – older doors may not be compatible with all modern locking systems. Furthermore, look beyond just the initial cost; some high-security handles come with significantly higher installation costs due to their more complicated fitting requirements.

Another area where UK shoppers frequently fall short is considering the ongoing running or fitting costs associated with a particular handle. While a simple lever handle might appear economical in terms of upfront purchase price, consider the potential for replacement parts over its lifespan. High-quality handles from reputable manufacturers will naturally last longer, but even they require occasional lubrication and maintenance. More complex locking systems – particularly those incorporating smart home technology – often have higher ongoing costs due to battery replacements or subscription fees. Researching the availability of spare parts and the long-term cost of upkeep should be part of your decision-making process. Don't just focus on the initial price tag; think about the total cost of ownership over several years.

It’s also vital to resist being swayed purely by marketing hype or a headline specification that seems impressive but is ultimately irrelevant for everyday use. Many manufacturers will highlight features like "anti-tamper" mechanisms or “keyless entry” in their brochures, creating an impression of superior security or convenience. However, these features often come with a significant price premium and may not be necessary for the vast majority of homeowners. A well-fitted, robust lever handle with a reliable key lock is perfectly adequate for most domestic situations. Don’t fall into the trap of believing that every handle needs to be “smart” or “ultra-secure.” Prioritize functionality and durability over unnecessary bells and whistles – you'll save yourself money in the long run.

Finally, don’t underestimate the importance of professional installation. While some homeowners may attempt DIY installations with varying degrees of success, installing door handles and knobs correctly is a skilled task that requires precision and knowledge. Improper fitting can lead to loose handles, damaged doors, or even security vulnerabilities. The cost of a qualified locksmith or ironmonger to install your new hardware might seem like an added expense, but it’s often far cheaper than dealing with the consequences of a poorly executed installation – including potential damage to your door and the need for costly repairs. Always factor in professional fitting costs when budgeting for your purchase and ensure that the installer is experienced and qualified to work with the specific type of handle you've chosen. Check references and ask about their experience with similar installations before committing to their services.
